A person jumps odd the top of a building which is 12 metres above ground. She is attached to the end of the bungie cord (a big rubber band) that has an unstretched length of 6 metres. The cord stretches until the physics major is stopped 2 metres above the ground. She then bounces back upward and begins oscillating (bouncing up and down). The student's mass is 55kg. Ignore air resistance. a) what is student's total energy after oscillations begin? b) what is spring constant k for bungie cord? c) what is frequency of her oscillation? d) how long does it take her to travel up and down 4 times ( how long does it take her to complete 4 oscillation)? e) what is the amplitude of resulting oscillation? f) what is her maximum speed after the oscillation begins?

A hot-air balloon is initially floating (stationary) a few metres above the ground. The radius of the spherical balloon is 6.25 m, and the density of surrounding air is 1.29 kg m-3. "Ballast" is weight of negligible volume that can be dropped to make the balloon rise. How much weight would you have to drop overboard to make the balloon rise 105 m in 15.0 s? You may assume that the density of surrounding air remains constant.
